Questions about this item

How often will the 12V 3.5AH SLA battery need replacing?

The manufacturer states an expected service life of 4 to 7 years; the sealed AGM design is maintenance-free, so no topping up or periodic servicing is required.

What limits continuous runtime when the UPS is on battery?

The 3.5 Ah capacity determines how long the UPS can supply power; once that stored energy is depleted the battery must recharge before it can support another outage.

Does the battery generate noticeable heat or noise during all-day float charging?

Sealed AGM construction produces no audible noise; under normal float conditions heat output is minimal and the compact 5.28 × 2.64 × 2.4 in case dissipates it passively.
